Title:
PHOTOSENSITIVE RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2878039
Kind Code:
B2
Abstract:
PURPOSE: To provide a photosensitive resin compsn. having good sensitivity and light-shielding property after cured.
CONSTITUTION: This photosensitive resin compsn. is prepared by adding C.I pigment black 7, C.I. pigment blue 15.6, C.I. pigment red 177 and C.I. pigment yellow 139 as the light-shielding dyestuff, to methacrylic acid/methyl methacrylate copolymer (25/75wt% ratio), pentaerithritor tetraacrylate, diethylthioantone, mihillers ketone, 2-(o-chlorophenyl)-4,5-diphenylimidazolyl dimer, and ethylene glycol monoethyl ether acetate, kneading the mixture, and filtering. The obtd. resin compsn. is applied on a glass substrate 1, heated and dried. Then a 10% aq. soln. of polyvinylalcohol is applied by spin coating, heated and dried to form a photosensitive resin layer 2. The photosensitive layer is exposed to light and developed with 0.5% aq. soln. of sodium carbonate.
